The Multiquip 2542120101 Crankshaft Complete is a genuine OEM component designed for BA-Series walk-behind power trowels. This is a direct OEM replacement sourced through Multiquip's authorized parts program, ensuring the part meets the same specifications as the original installed unit. The 2542120101 is the correct crankshaft assembly for BA-Series trowels, giving you confidence in fitment before the part ever arrives on site. If your BA-Series trowel is showing signs of engine wear or crankshaft failure, this is the part to have on hand.
Key Features
- Genuine OEM Crankshaft Integrity — Machined to the same dimensional tolerances as the original crankshaft, maintaining proper bearing journal clearance and counterweight balance critical to smooth engine operation.
- Drop-In Engine Assembly Fit — Engineered to seat correctly within the engine block of BA-Series trowels, aligning with connecting rod, main bearings, and flywheel without modification.
- BA-Series Walk-Behind Trowel Compatibility — Confirmed fitment for Multiquip BA-Series 46-inch walk-behind power trowels, one of the most widely used finishing machines in flatwork concrete crews.
- Full Power Stroke Restoration — A worn or damaged crankshaft causes vibration, loss of power, and uneven blade speed; replacing it with this OEM assembly restores consistent RPM delivery to the trowel gearbox.
- Long-Term Engine Reliability — As a complete crankshaft assembly, this part replaces the entire rotating component in one service event, avoiding the compounding wear risk of reusing a compromised shaft.
The crankshaft is the central rotating shaft inside the engine that converts the up-and-down motion of the piston into rotational power. On a walk-behind trowel, that rotational power drives the gearbox and ultimately spins the finishing blades across the concrete surface. When a crankshaft becomes worn, bent, or scored at the bearing journals, the engine produces excessive vibration, loses power output, and can cause accelerated wear on the connecting rod and main bearings. Replacing the crankshaft complete restores the engine's mechanical foundation and returns the trowel to smooth, consistent operation.
